There is no Beta 4 rar, and if I remember correctly Beta 3 is packaged as a 7z file. Sounds like you’re trying to open it with an extraction software that doesn’t support 7z. You can get 7zip to extract it, it’s free: https://www.7-zip.org/download.html

This kind of reminds me of some of the crazy things people do in Mario Maker, just way more extreme. I love it!
That’s some pretty damn good stuff.
